This paper stages an encounter between Foucault and Althusser on the question of strategy. By contrasting a few passages in La Volonté de savoir with some of Althusser’s writings on Machiavelli and Lenin, I propose an alternative between the two thinkers according to a schema of strategic thought (Foucault) and a philosophy for strategy (Althusser). This narrow focus enables me to generate a working definition of strategy as the anticipation of an encounter which modifies, abolishes, or otherwise alters the relations (...) constituting its conjuncture. By staging the encounter between the Foucault and Althusser, I propose this definition as a reflection on the phrase “intervention into conjuncture,” and conclude by sketching implications concerning theory, practice, and the discipline of the conjuncture.
